Title: Hoisting device for sheathing board
Inventor: KOMIYAJI KAORU
IPC: E02B7/40
Filed: 1995-05-27
Abstract: PURPOSE: To obtain a power type small-sized lightweight hoisting device, for which heavy labor is not required and which has comparatively simple structure and construction cost of which is reduced, by installing a speed reducer, in which an output shaft can be connected to a handle shaft for hoising and an input shaft to the shaft of an electric drill respectively. CONSTITUTION: The shaft of an electric drill 40 on the market is coupled with the input shaft of a speed reducer 35 in a mutually independent unturned manner. A charging type battery 47 is mounted at the lower end section of the electric drill 40. When the output shaft of the speed reducer 35 is joined with the input shaft 7 of a hoisting device body la and the electric drill 40 is started, the revolving power of the electric drill 40 is transmitted to the input shaft 7 through a decelerating mechanism in the speed reducer 35, and a pulley 10 is rotated through a hoisting mechanism in the hoising device body la. Accordingly, a wire 12 suspending a sheathing board 20 is wound on the pulley 10, and the sheathing board 20 is erected gradually.  When a fixed quantity of the wire 12 is wound and the sheathing board 20 is erected sufficiently, a power supply for the electric drill 40 is disconnected. Accordingly, no large labor is required for hoising, thus easily conducting operation.

Filed: 1990-06-11
Abstract: PURPOSE:To obtain a hard copy selectively from picture information on plural display devices by synchronizing video signals of different video frequencies individually with a video signal input timing of a hard copy control means respectively. CONSTITUTION:Switches S1-Sn are selected in response to a video frequency of separate display devices 11a, 11b. Then A synchronizing signal generating circuit 24 in video signal input circuits 13a, 13b generates a synchronizing clock signal to synchronizing the signal input timing of a hard copy control circuit 15 with the video signal frequency of the display devices 11a, 11b thereby synchronizing the video signals through a synchronizing circuit 22. Thus, the user selects optionally display picture information in the display devices 11a, 11b by having only to switch a changeover circuit 14 to obtain a hard copy. Thus, a hard copy is obtained selectively from displayed picture information by one hard copy equipment.

Title: Holding device
Inventor: HAYASHIDA MASAYUKI
IPC: H05K13/04
Filed: 1987-06-19
Abstract: PURPOSE:To improve part installing efficiency to a substrate by making it possible to adjust the interval size between a pair of holding pawls having a push rod between them by means of a stepped pin so as to make a pitch between part legs constant even for a part with legs of different thickness. CONSTITUTION:Holding pawls 12, 12 having a push rod 13 between them are disposed along supporting wall parts 11a, 11a at the lower end of the main body 11 of a holding device to be energized by a spring 18 in the direction to contact with each other. A semicircular cut is formed almost at the center of the guide part to each holding pawl 12, 12, where a stepped pin 15 is inserted. By moving the stepped pin 15 to slide by a cylinder, the cuts in the holding pawls 12 are opened or closed laterally by different diameters of the stepped pin, so the interval between the holding pawls 12, 12 is changed. In case thickness of the legs of a part is different, the pitch for the lead part folding size for the part can be made constant, thereby installation of a part to a substrate can be performed without replacing holding pawls.

Title: Method for adjusting optical axis of infrared-ray optical system
Inventor: KAMOZAWA MAKOTO
IPC: G02B7/00
Filed: 1989-06-15
Abstract: PURPOSE:To easily align the optical axis of a lens with the center axis of rotation of a lens barrel as to the infrared-ray optical system which does not transmit visible light by forming a projection or recessed part in the surface of the lens. CONSTITUTION:The lens 1 is fixed to the lens barrel 2 with an adhesive 4 after being adjusted with an adjusting screw 3. The projection part 5 is formed of the same material with the lens on the lens surface. The optical axis is aligned by observing the projection part 5 through a microscope 6 from the left side of the lens after the lens 1 is fixed temporarily. In this state, the lens barrel 2 is rotated on the center axis A of rotation. An observed image of the projection part through the microscope 6 shows that the projection part 5 rotates around off the area unless the lens is aligned correctly with the center axis A of rotation of the lens barrel. Here, the projection part comes to rotate on one point in the area by moving the lens slightly in a plane perpendicular to the optical axis with the adjusting screw 3.

Title: Alarm circuit
Inventor: NISHIHAMA YASUO
IPC: G11B33/10
Filed: 1978-12-11
Abstract: PURPOSE: To prevent the recording failure due to the dust sticking or the like through generation of the alarm by detecting that the difference becomes outside the fixed range between the record and reproduction output levels of the magnetic tape recorder.  
     CONSTITUTION: The signals recorded on magnetic tape 5 through recording head 4 are reproduced through reproduction head 6. And the reproduction level signal passing through diode 32 is compared at comparator 34 with the record level signal passing through diode 30. Comparator 34 does not generate the comparison output as long as the difference between the both level signals is normal within the fixed range. And in case the record or reproduction output level lowers down due to the dust or the like sticking to tape 5 and others to set the difference between the both evel signals outside the fixed range, the comparison output is generated. Thus alarm lamp 35 or the like is lit up to announce the fault occurrence. In such constitution, the recording failure due to sticking of the dust or the like can be prevented in a easy and assured way.
